About Cats’ WhiskersCats’ whiskers are once called “the sixth receptor.” These whiskers possess such precise sensibility that even a movement as inconspicuous as 1/2000 of the diameter of human hair can be sent to cats’ brain instantly. Anatomists refer to cats’ whiskers as tentacle, and they are used to detect prey, to measure and to give warning to cats about invisible obstacles. Besides, whiskers can also detect wind direction and air currents, thus helping cats determine the location of prey. Whiskers can also guide cats in darkness. If a cat unfortunately loses her whiskers, they can only depend on eyes for direction and to hunt.
